Title: Floppy disk control system
Inventor: TAKAGI KAZUO
IPC: G11B21/12
Filed: 1978-09-22
Abstract: PURPOSE: To increase the life time of the floppy disk and thus to enhance the reliability by positioning forcedly the head to the specified track designated previously when no read/write is given to the floppy disk and thus limiting the abrasion of the magnetic surface only to the specified track.  
     CONSTITUTION: The seek signal is delivered from decorder 23 of floppy control unit 18 and applied to timer 24 and selector 28. And selector 28 selects the signals of signal line 25 as soon as timer 24 starts clocking, and the selected signal is supplied to track address register 35. And in case no subsequent signal is supplied even for the while longer than the set time of timer 24 after the last seek signal came in, timer 24 generates output 27. At the same time, selector 28 selects track number data line 26 sent from fixed constant generator 25 and then registers the specified number given from generator 25 to register 35 to shift the head to the specified track. Owing to this shift, the heas abrasion is limited only to the specific track, thus increasing the life time of the disk.

Abstract: PURPOSE:To recover the noble metal in a Cu electrolysis slime in high yield by melting the slime freed of copper and selenium along with a carbonaceous reducing agent and incorporating Sb in the slime into slag and the noble metal into noble metal-contg. lead. CONSTITUTION:Crude copper is electrolyzed to produce high-purity electrolytic copper. In this case, since the slime deposited on the bottom of an electrolytic cell contains metal elements such as Au, Ag, Sb, etc., copper and selenium are firstly removed, a carbonaceous reducing agent is added in the stoichiometric equivalent necessary to reduce all the remaining Cu and Bi and 60-100wt.% of Pb, <=4wt.% of a silica-based flux is added, as required, and the mixture is melted. Sb in the slime is mostly incorporated into slag and the noble metal into Pb to form noble metal-contg. lead. The noble metal-contg. lead is heated and volatilized to recover Au and Ag in extremely high yield, and Sb is transferred to the noble metal-contg. lead from the slag. separated and recovered by oxidizing volatilization.

Title: Projecting method of synchrotron radiation
Inventor: NISHIBE TATSUO
IPC: H05H13/04
Filed: 1987-05-16
Abstract: PURPOSE:To facilitate the uniform projection of radiation and the size reduction of equipment by a method wherein the radiation is successively reflected by a pair of mirrors provided in parallel to each other and one of the mirrors is shifted in parallel so as to increase an application area. CONSTITUTION:If a synchrotron radiation is successively reflected by a pair of mirrors 2 provided in parallel to each other, the light entering a pair of the mirrors 2 and the light outgoing from the mirrors 2 are always in parallel to each other so that the synchrotron radiation in the horizontal direction which is taken out of the orbits of electrons can be applied to an object while the horizontal direction is maintained. Therefore, a wafer 3, a pattern mask 4 and so forth which are the exposed surfaces can be prepared vertically without being inclined. Moreover, if the reflected light is moved in a parallel plane while the angle of incidence of the radiation is kept constant to increase an application area, as the angle of incidence is not varied, the uniform application can be realized only by moving the mirror in parallel at a constant speed with out changing the spectrum and intensity of the light reflected by the mirrors. Further, as the distance between the mirrors and the exposed object need not be large, the size of the equipment can be reduced.
